MACHINE FOR STRAIGHTENING SHEETS OF PAPER.

SPECIFICATION forming part of Letters Patent No. 418,310, dated Deceinber 31, 1889.

Application led December 26, 1888. Serial No. 25M-.,714f (No model.)

.T0 if/Z wil/0711, it may concern:

Be it known that I, CHARLES MILTON Corr, a citizen of the United States, residing at the city of Meadville, in the county of Crawford and State of Pennsylvania, have invented a` loose sheets of the tablets are placed to square and straighten up before being clamped and glued. A A are the two sides of the trough, fastened together at right angles to each other and supported by the two supports I I, as shown in the drawings. This trough is Open at one end, and the other end has a notch at E to permit the adj ustinent of a clamp.

Fig. 2 represents the tablet B removed from t-he trough, with the clamp O attached thereto. This clamp is constructed in the usual form, witha straightbar of iron bent at right angles at one end, through which is a thumb-screw D. At O there is a sliding bar, as shown in the drawings, Fig. 2.

Fig. 3 is a board Of a sine suitable to fit the trough and the size of the paperto be tableted. In one side Of this board is anotch II, extending from thev edge toward the center, so that the clamp can be adjusted to various-sized paper, the screw-bearing being exactly in the center of the paper to be clamped. The pressboards L and F are beveled on their edges, as shown at Fig. 2.

In operating my device the pressboardF is placed in the trough so that the notch H willcorrespond with the notch E. The paper to be tableted is placed in the trough against the board F. Then the board L is put in place, as shown in drawings, the clamp adjusted, and the screw D turned tightly, when the tablet can be lifted out, so that the edges can be glued on the sides which were next to the trough.

Vhat I claim as my invention, and desire to secure by Letters Patent, is as follows, to Wit:

The combination, with the box A, havin g in one end the notch E,Aof the clamp-boards F and L, board F having a notch H registering with the notch E, and the screw-clamp C D, the screw D engaging the board F and the clamp O comprising a sliding bar engaging the board L, substantially as set forth.

CHARLES MILTON GOTT.
